19. Guettarda calcicola sp. nov. 



A tree up to 5 m. high, with slender branches, the young twigs 

 densely appressed-pubescent. Stipules ovate, appresscd-pubes- 

 cent with long hairs, about 4 mm. long; leaves oblong-elliptic to 

 ovate-lanceolate, membranous, 4-8 cm. long, 3.5 cm. long or less, 

 acuminate at the apex, acute or acuminate at the base, shining, 

 prominently pinnately veined, with slender, ascending veins, 

 loosely reticulate-veined and sparingly appressed-pubescent on 

 the veins above, appressed-silky beneath, the slender petioles 

 3-8 mm. long; inflorescence axillary; peduncles slender, as long 

 as the leaves or shorter, several-flowered; calyx subtruncate, 

 appressed-pubescent, about 1.5 mm. long; young fruit oblong to 

 oblong-obovoid, densely finely appressed-pubescent, about 5 mm.

20. Guettarda Lindeniana A. Rich, in Sagra, Hist. Cub. 11: 



20. 1850 

 Type locality: Near Santiago, Cuba. 



Distribution: Lower and middle elevations, Oriente. En- 

 demic. 



21. Guettarda brevinodis Urban, Symb. Ant. 7: 404. 1912 



Type locality : Cuba. 



Distribution: Rocky limestone hills, Pinar del Rio. Endemic. 

 This does not appear to me to be certainly distinct from the 

 following.

 Type locality : Cuba. 



Distribution: Known only from the type specimens {Wright 

 2702, in part), their exact station not recorded. This and the 

 preceding species were referred by Grisebach to G. membranacea 

 Sw., of Hispaniola, and by Wright to G. Lindeniana A. Rich. 



23. Guettarda elliptica Sw. Prodr. 59. 1788
